Research On Technology Of Twin-cutter NC Turning Programmming

There are two cutters in twin-cuter turning process, which is able to shorten man-hour and improve production efficiency, and it is widely used in mass production. But it is difficult to design its NC (Numerical Control) program.Interactive interfaces of process and dealing with tinformation of process has been finished. The main contents are as following:1. An overview on current situation of NC technology is discussed. Their features of structure and function are discussed. Speeding up the domestic numerical control system by the latest technology of PC have been proposed2. Features and application field of typical programming method, such as manual programming and automatically programming are expounded.VC.NET and ObjectARX are discussed.3. Development of AutoCAD menu has been lucubrated, includeing translation of menu, loading of menu, unloading of menu and the type of menu file.The interactive interfaces of process has been finished.4. Assigning principle of two turrets is researched. The planning method of cut-in segment, cuting segment, cut-out segment, and their cutting parameters are disscussed.The scheduling problem of geometrical information is realized by the point of entity comparison method, while the linked list-CList is used to solve the storage and modification of the machining technological parameters.
